2. 1. Phase-Noise Compensation for Space-Division Multiplexed Multicore Fiber Transmission

   Author : Arni Alfredsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; detection; estimation; space-division multiplexing.; phase noise; multicore fiber; Coherent fiber-optic communications;

   Abstract : The advancements of popular Internet-based services such as social media, virtual reality, and cloud computing constantly drive vendors and operators to increase the throughput of the Internet backbone formed by fiber-optic communication systems. Due to this, space-division multiplexing (SDM) has surfaced as an appealing technology that presents an opportunity to upscale optical networks in a cost-efficient manner. READ MORE

   Abstract : The protection of confidential data is a fundamental need in the society in which we live. This task becomes more relevant when observing that every day, data traffic increases exponentially, as well as the number of attacks on the telecommunication infra-structure. READ MORE

5. 3. Compensation of Laser Phase Noise Using DSP in Multichannel Fiber-Optic Communications

   Author : Arni Alfredsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multichannel transmission; rotations; digital signal processing; laser phase noise; Coherent fiber-optic communications; detection; estimation;

   Abstract : One of the main impairments that limit the throughput of fiber-optic communication systems is laser phase noise, where the phase of the laser output drifts with time. This impairment can be highly correlated across channels that share lasers in multichannel fiber-optic systems based on, e.g. READ MORE

6. 4. Characterisation of Optical Fibers Using Dual-Comb Swept-Wavelength Interferometry

   Author : Ekaterina Deriushkina; Chalmers tekniska högskola; []
